Fading Supernova Seen In Lopsided Spiral Galaxy
2013-03-20 06:04:32

Lee Rannals for redOrbit.com - Your Universe Online Astronomers studying a violent explosion located 35 million light-years away from Earth in spiral galaxy NGC 1637 have provided a new view of the cosmic beauty. The team used the European Space Observatory's Very Large Telescope (VLT) at the Paranal Observatory in Chile to provide the new image. Scientists first reported the discovery of the supernova SN 1999em in the spiral galaxy NGC 1637 back in 1999. SN1999em was discovered by...

X-ray Emissions A Tell-tale Sign Of Supernova Birth

April Flowers for redOrbit.com - Your Universe Online A new study led by the University of Leicester has revealed new evidence suggesting X-ray detectors in space could be the first to witness new supernovae that signal the death of massive stars. An excess of X-ray radiation has been observed in the first few minutes of the collapse of massive stars. This excess may be the signature of the supernovae shock wave as it first escapes from the star. Dr. Rhaana Starling of the University...

WASHINGTON, Jan. 27 /PRNewswire-USNewswire/ -- Astronomers studying two exploding stars, or supernovae, have found evidence the blasts received an extra boost from newborn black holes. The supernovae were found to emit jets of particles traveling at more than half the speed of light. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO ) Previously, the only catastrophic events known to produce such high-speed jets were gamma-ray bursts, the universe's most luminous explosions....

Astronomers studying two exploding stars, or supernovae, have found evidence the blasts received an extra boost from newborn black holes. The supernovae were found to emit jets of particles traveling at more than half the speed of light. Previously, the only catastrophic events known to produce such high-speed jets were gamma-ray bursts, the universe's most luminous explosions. Supernovae and the most common type of gamma-ray bursts occur when massive stars run out of nuclear fuel and...

A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts. The object, SN 2008D, is thus probably among the weakest explosions that produce very fast moving jets. This discovery represents a crucial milestone in the understanding of the most violent...

Thanks to a fortunate observation with NASA's Swift satellite, astronomers, for the first time, have caught a normal supernova at the moment of its birth--the first instant when an exploding star begins spewing its energy into space, transforming into a supernova that during its brief lifetime will shine brighter than billions of stars combined. Until this discovery, the only supernovae glimpsed during their first moments were the more rare kind--the ones whose birth cries are drowned out by...

In just the past six weeks, two supernovae have flared up in an obscure galaxy in the constellation Hercules. Never before have astronomers observed two of these powerful stellar explosions occurring in the same galaxy so close together in time. The galaxy, known as MCG +05-43-16, is 380 million light-years from Earth. Until this year, astronomers had never sighted a supernova popping off in this stellar congregation. A supernova is an extremely energetic and life-ending explosion of a star....

Scientists using NASA's Swift satellite have observed two dozen recent star explosions, called supernovae, quickly after the event and have discovered never-before-seen properties, some of which run counter to prevailing theories. In one observation, they have confirmed the origin of Type Ia supernovae, an important class of explosions used to measure distances and dark energy. In other observations they have found new mechanisms to produce X-rays and ultraviolet light. The findings have...

ESA -- Scientists have found that a star that exploded in 1979 is as bright today in X-ray light as it was when it was discovered years ago, a surprise finding because such objects usually fade significantly after only a few months. Using ESA's XMM-Newton space observatory, a team of astronomers has discovered that this supernova, called SN 1979C, shows no sign of fading. The scientists can document a unique history of the star, both before and after the explosion, by studying rings of light...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
